Magnesium for Period Pain: Which Form and How Much
By Flexies Team
Magnesium has become one of the go-to daily minerals for cycle comfort. But scroll TikTok and you'll see glycinate, citrate, oxide, threonate — and a lot of conflicting advice on how much.
Here's the honest, jargon-free version.
The short answer
Magnesium glycinate is the form most women choose for cycle comfort because it's gentle on digestion and well-tolerated for daily use.
Take it daily across the whole cycle, not just on cramp day. The effect builds.
Why glycinate, specifically
Glycinate is magnesium bound to glycine, an amino acid. It's gentle on the gut and is the form most often suggested for evening rituals and cycle support.
Magnesium citrate is also common but can have a laxative effect, which isn't what you want during your period.
Oxide is cheap and poorly absorbed. Skip it.
How much, and when
Daily intake recommendations for adult women sit around 310 to 320mg from food and supplements combined, depending on age and life stage.
Most women take their magnesium glycinate as part of their evening wind-down, which has the bonus of supporting sleep.
On cramp days, take it as usual, not double. The benefit is from daily, not from heroic single doses.
What to pair it with
Magnesium pairs well with GLA-rich oils like evening primrose and starflower, which are traditionally used to support the lead-up to your period.
Many women run Wind Down Sleep Gummies (magnesium glycinate + L-Theanine) in the evening and PMS Relief Gummies (evening primrose, starflower, maca) in the morning across the whole cycle.
When you should notice a difference
Most women notice subtle changes by the end of cycle one, and more meaningful comfort improvements by cycle 2 to 3.
Consistency is the lever. Daily wins over heroic.
